CONDUIT FOR-CABLE ORiELECTRICAL RA'l LWAYS.

' SPECIFICATION forming part of Letters ;Patent No. 315,841, dated April1%; 1885.-

Application filed March: 6, 1885. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD SAMUEL, a citizen of the United States, and aresident of Philadelphia, Pennsylvania, have invented certainImprovements in Conduits for Cable or Electrical Railways, of which thefollowing is a specification. g

The object of my invention is to provide the conduit of a cable orelectric railway with slot-irons, which, while firmly supported upon theconduit, can be readily adjusted laterally thereon to increase ordiminish the width of the slot, and can be readily removed andv replacedwithout entering'or disturbing the main structure of the conduit ortearing up the street-pavement, and without interfering with the runningof the cars. 7 I I In the accompanying drawings, Figure 1 is aperspective view of a section of street with my improved conduit; Fig.2, a transverse section of the upper portion of the conduit, showing myinvention; Fig. 3, an inverted sectional plan on the line 1 2, Fig. 2;and Figs. 4 and 5, views illustrating modifications of the invention.

A A are bars forming the upper portions of the opposite sides of theconduit. These bars may be integral with said sides, or may be separatepieces attached thereto, as preferred.

As shown in Fig. 1, each bar A terminates at the top in a verticalflange, a, at the base of which are inner and outer horizontalshoulders, b I).

Embracing the flange a of each bar A is a channel-bar, B, or, as it isusually termed, a slot-iron, the web l of which bears upon and issupported by the top of the flange a, the opposite wings or flanges f fof the slot-iron resting upon the shoulders b b of the bar A, which thusassist the flange a in supporting the said slot-iron.

The slot 9, for the passage of the grip or conductor bar, is bounded bythe inner edges of the ribs h on the slot-irons B, and in order that thewidth of the slot may be increased or diminished as desired, thedistance between the flanges ff of each slot-iron is greater than thewidth of the flanges a of the supportingbars A, so that lateraladjustment of the slot irons on the bars is permitted. This adjustmentis effected by means of set-screws m and n, which, in the presentinstance, alternate with each other throughout the length of theconduit. threaded openings in the outer flange, f, of each slot-iron B,and bear against the outer The set-screws m are adapted to face of theflange a, of the bar A, and the setscrews a pass through openings in theouter i flange, f, of the slot-iron, .and are adapted to threadedopenings in the flange a, and bear upon the inner flange, f, of saidslot-iron. The

setscrews m thus serve to limit the inward movement of the slot-iron,and the screws a limit the outward movement of the same, so

that by properly manipulating both sets of screws the lateral adjustmentof the slot-irons on the bars A can be effected as desired. the; saidslot-irons being firmly locked in position after adjustment bytightening both sets of duit, angle or T bars may be used if desiredf'as shown in Figs. 4 and 5, some of the setscrews being adapted tothreaded openings in the flange of the slot-iron and others to threadedopenings in the flange of the supporting-bar A, so as to provide foradjustment and looking of the slot-irons on the supporting-bars, asabove set forth.

The heads of the adjusting-screws m and n are preferably contained inboxes or casings x at the sides of the conduit, these boxes havingremovable'covers y flush with the pavement, so as to permit ready accessto the screws when it is desired to adjust or remove the slot-iron, forit will be observed that the lateral adjusting-screws also serve to keepthe slot-iron vertically in position on the conduit, so that onwithdrawing said screws the slot-iron can be readily removed, whennecessary-as, for instance, when said slot-iron has become worn, or whenit is desired to gain access to the inside of the conduit from the top.

Conduits with laterally-adj ustable slot-irons have been heretoforedevised, as shown, for instance, in my Patent No. 282,7 83, dated August7, 1883, and therefore I do not claim, broadly, a laterally-adj ustableand verticallyremovable slot-iron.

The advantage of the present construction is, that the adjustment; orremoval of the slotiron can be effected without anydisturbance of thestreet-pavement, without stopping the running of the cars, and withoutthe necessity of going inside the conduit, the slot-irons and theiradjusting and securing devices being within the limits of the opening inthe streetpavement, and said adjusting and securing devices beingaccessible from the surface of the street.

I prefer to so construct the parts that the lateral movement of theslot-irons will be sufiicient to expand the slots to such an extent asto permit the lifting of the traction-cable or electrical conductor fromthe conduit through said slot, so that repairs can be made at anydesired spot, the necessity of drawing the defective portion of thecable or conductor to a man-hole or station being obviated.

The conduit may have a removable and adjustable slot iron on one sideonly, if desired; but it is preferable to adopt the construction shownin the drawings.

'1 claim as my invention 1. Acable or electrical railway conduit havinga detachable slot-iron contained within the limits of the opening in thestreet-pavement, and combined with securing devices ac cessible from thesurface of the street, all substantially as specified.

2. The combination ofa cable or electrical railway conduit with alaterallyadjustable slot-iron and adjusting devices therefor containedwithin the limits of the opening in the street-pavement, and accessiblefrom the surface of the street, as set forth. 4

The combination of a cable or electrical railway conduit with aremovable and laterally-adjustable slot-iron, and with transverseset-screws serving both to adjust said slotiron and to confine the samevertically to the conduit, as set forth.

4. The combination of the bar A, secured to or forming part of aconduit, with the slotiron B, adjustable laterally on the bar, and withtwo sets 'of adjusting devices, one controlling-the movement of theslot-iron in one direction, and the other controlling its movement inthe opposite direction, as specified.

5. The combination of the bar A, secured to or forming part of aconduit, and having a shoulder below the top, with a slot-iron havingone support upon the top of the bar and another on the shoulder belowthe top, as set forth.

6. The combination of the bar A, secured A to or forming part of aconduit, with the channel-barB, occupying an inverted position over thetop of the bar A, and forming the slot-iron of the conduit, and withdevices for laterally adjusting said slot-iron, as set forth.

7. Thecombination of the bar A, secured to or forming part of a conduit,the laterallyadjustable slot-iron B, and the two sets of transverseadjusting-screws m and n, one set of screws having a bearing on the barand being adapted to threaded openings in the slot-iron, and the otherset having a bearing on the slotiron and being adapted to openings inthe bar, as set forth.

, In testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.
